Company Reports Advancements in Neurology-Focused Pipeline and Anticipates Multiple Products in Phase 2 or Later Stage Development this Year

Conference Call at 4:30 pm ET Today

BURNABY, British Columbia, May 07, 2019 (GLOBE NEWSWIRE) -- Xenon Pharmaceuticals Inc. (NASDAQ:XENE), a clinical stage biopharmaceutical company, today reported its financial results for the first quarter ended March 31, 2019 and provided a corporate update.

Dr. Simon Pimstone, Xenon's Chief Executive Officer, said, "We continue to make significant progress advancing our robust, novel pipeline comprised of neurology-focused product candidates, including XEN496, XEN1101, XEN901, and XEN007. Supported by a strong balance sheet, we are executing our clinical development plans with the goal of having multiple products in Phase 2 or later stage development this year. Some important anticipated milestone events include: initiating a Phase 3 clinical trial for XEN496 for the treatment of KCNQ2 epilepsy; further advancing our ongoing XEN1101 Phase 2b clinical trial in adult focal epilepsy; and initiating a Phase 2 clinical trial for XEN901 in either a pediatric or adult epilepsy indication depending on regulatory feedback. In addition, we expect to initiate a Phase 2, or later stage, clinical trial for XEN007 in an orphan neurological indication."

Achievements and Anticipated Milestones

  • XEN496 (active ingredient ezogabine) is a Kv7 potassium channel modulator being developed by Xenon. The FDA has granted orphan drug designation (ODD) for XEN496 as a treatment of KCNQ2 epileptic encephalopathy (KCNQ2-EE). Xenon is currently finalizing a pediatric-specific formulation to complete pre-clinical formulation testing with a final drug product expected in the second quarter of 2019. Xenon is planning to test the XEN496 pediatric formulation in a study of healthy adult volunteers, which is expected to be initiated in the third quarter of 2019. Xenon expects to file an Investigational New Drug (IND) application in the fourth quarter of 2019 to initiate a Phase 3 clinical trial in KCNQ2-EE. The FDA has indicated that it is acceptable to study XEN496 in infants and children up to 4 years old, and that a single pivotal trial in approximately 20 patients may be considered adequate in order to demonstrate XEN496's efficacy in KCNQ2-EE.
     
  • XEN1101 is a differentiated Kv7 potassium channel modulator being developed for the treatment of epilepsy and potentially other neurological disorders. Xenon has initiated a Phase 2b clinical trial, which is designed as a randomized, double-blind, placebo-controlled, multicenter study to evaluate the clinical efficacy, safety and tolerability of XEN1101 administered as adjunctive treatment in approximately 300 adult patients with focal epilepsy. The primary endpoint is the median percent change in monthly focal seizure frequency from baseline compared to treatment period of active versus placebo. Site selection and patient enrollment are now underway for the XEN1101 Phase 2b clinical trial in the United States, Canada and Europe. Depending upon the rate of enrollment, top-line results from the XEN1101 Phase 2b clinical trial are anticipated in the second half of 2020.
     
  • XEN901 is a potent, highly selective Nav1.6 sodium channel inhibitor being developed for the treatment of epilepsy. Results from a XEN901 Phase 1 clinical trial and related pilot TMS study were announced in December 2018. The next steps for XEN901 include continued planning for Phase 2 or later clinical development to evaluate XEN901 as a treatment for rare, pediatric forms of epilepsy, including SCN8A epileptic encephalopathy (SCN8A-EE) or adult focal seizures, depending on feedback from regulatory agencies. Xenon expects to receive feedback on the requirements to advance XEN901 into pediatric SCN8A-EE patients in the second quarter of 2019. In order to support future pediatric development plans, juvenile toxicology studies and pediatric formulation work are underway.
     
  • XEN007 (active ingredient flunarizine) is a CNS-acting calcium channel modulator that modulates Cav2.1 and T-type calcium channels. Other reported mechanisms include dopamine, histamine and serotonin inhibition. Available in certain countries outside of the United States, flunarizine has been reported to have clinical benefit in treating migraine and other neurological disorders, including hemiplegic migraine (HM), alternating hemiplegia of childhood (AHC), vertigo, and as an adjunctive treatment in certain epilepsies, including childhood absence epilepsy. The FDA granted a rare pediatric disease designation for the treatment of AHC with XEN007, and previously granted ODD for XEN007 as a treatment of both AHC and HM. To support the advanced clinical development of XEN007, Xenon has entered into key licensing and manufacturing agreements. Various development strategies for XEN007 are under consideration, including the support of at least one Phase 2 (or later stage) clinical trial in an orphan neurological indication, with initiation anticipated in 2019.

First Quarter 2019 Financial Results

Cash and cash equivalents and marketable securities as of March 31, 2019 were $110.4 million, compared to $119.3 million as of December 31, 2018. There were 25,771,954 common shares and 1,016,000 Series 1 Preferred Shares, which are convertible into common shares on a one-for-one basis at the option of the holder, subject to certain limitations, outstanding as of March 31, 2019.

Based on current assumptions, which include fully supporting the planned clinical development of XEN496, XEN1101, XEN901 and XEN007, Xenon anticipates having sufficient cash to fund operations into 2021, excluding any revenue generated from existing partnerships or potential new partnering arrangements.

Research and development expenses for the quarter ended March 31, 2019 were $9.1 million, compared to $5.6 million for the same period in 2018. The increase of $3.6 million was primarily attributable to increased spending on the XEN1101, XEN901, and XEN496 product candidates. These increases were partially offset by decreased spending on pre-clinical, discovery and other internal program expenses.

General and administrative expenses for the quarter ended March 31, 2019 were $2.6 million, compared to $2.2 million for the same period in 2018. The increase of $0.4 million was primarily attributable to increased legal expenses for intellectual property protection and business development expenses.

Other income for the quarter ended March 31, 2019 was $0.5 million, compared to $4.1 million for the same period in 2018. The decrease of $3.6 million was primarily driven by a one-time gain of $4.4 million recognized in March 2018 on the termination of the collaboration agreement with Teva Pharmaceuticals International GmbH, along with Teva Canada Limited (together, Teva), resulting from the cancellation of 1,000,000 common shares of Xenon that were owned by Teva, partially offset by an increase in interest income and a change in foreign exchange gains and losses arising largely from the translation of cash and cash equivalents and marketable securities denominated in Canadian dollars to U.S. dollars.

Net loss for the quarter ended March 31, 2019 was $11.3 million, compared to $3.8 million for the same period in 2018. The change was primarily attributable to the decrease in other income and higher research and development expenses.
